A continuous variable can take on any value within a given range and be subdivided into finer units. Weight is continuous because it can, in principle, be recorded with decimal precision such as 55.2 or 55.23 kilograms, making it suitable for many statistical techniques that assume continuity.

Option A:
This option refers to the number of students, which is a discrete variable because it can only take whole number values; you cannot have 30.5 students.

Option B:
This option correctly identifies weight measured on a metric scale as continuous; it can vary in very small increments and be represented by real numbers.

Option C:
This option describes type of school management, which is a categorical (nominal) variable rather than a continuous one.

Option D:
This option refers to gender categories such as male or female, which are also nominal and not continuous numerical measures.

Statement A correctly describes qualitative data as categorical. Statement B is true for quantitative data, which involve numerical magnitudes. Statement D is also correct, since continuous data can, in principle, assume any value in an interval with arbitrary precision. Statement C is false because discrete data take countable values with gaps, while continuous data take any value in an interval. Statement E is false as understanding data type helps in choosing appropriate measures and graphs. Hence, A, B and D only are correct.

Option A:
Option A is incomplete because it omits D (continuous data).

Option B:
Option B is correct since it includes all true statements and excludes C and E.

Option C:
Option C is wrong because it includes C (false).

Option D:
Option D is incorrect because it includes C (false) and omits B.
